Color psychology is the fascinating science of human the colors of the light spectrum influence our mood and behaviour. For example, placebo pills that are hot-colored tend to produce a stronger effect when patients believe they are taking stimulants, and light blue pills produce a stronger effect when they believe they are taking medication for depression.
According to a 1997 survey by Cooper Marketing Group, 35% of Americans say that their favorite color is blue, followed by followed by green (16%), purple (10%) and red (9%). It is believed that blue and green have such a calming and positive effect on people because of what we would have associated these colors with in our ancient history. 50,000 years ago, blue and green would mean water, food sources and shelter.
